Hello.
I've been hard-testing this week the 15th march version (mostly DNG) and I 've got very improved results, mostly about hot pixels.

Quite interesting. What kind of software did you use to get this improved results over JPEG?

Gurus,
I've built cross toolchain (on Linux) with binutils-2.18 and gcc-4.3.3 as described.
Building chdk for ixus980, I now get the failure that the processor would not support the "BLX R12" assembly instruction (in boot.c).
Is passing mcpu=arm946e-s -mfpu=fpa the right remedy? As I don't know the hardware, I'm especially doubtful on -mfpu=fpa ... Does the processor have an FPU? If so, shouldn't it be an vfp9?

Well, it compiles, but crashes on the camera. Not passing any -mcpu/-march switch (as it always seems to imply something about FPU availability that's not right) and then recompiling the single file that fails (boot.c) with -march=arm5vte to avoid the blx r12 message does the trick for me. I doubt that this is ideal or even clean. Resulting FW then works. (I have battery voltage limits and EFL corrected ...)

There is a long thread on gcc 4 confguration here (never mind the windows parts)

FWIW, the camera does NOT have an FPU.

Sorry I've been quiet lately on this thread, Real Life has been keeping me extremely busy. I should have a bit more time soon.

It's a patch against the CHDK source tree. Since you didn't recognize this, it's unlikely to be any use to you. If you want to use CHDK, use the build included in the zip.
